Definition of duxelles in English:

noun

He removes a circle from the middle, replaces it with crisp endive, then uses it as a lid over succulent slices of rabbit, stuffed with mushroom duxelles and its own kidney.

Escargots are baked in Pernod, butter, fennel, and duxelles of mushrooms.

One school argues that it was named after the Marquis d' Uxelles whose cook, La Varenne, wrote a popular cookery book in the 17th century (La Varenne himself, however, does not include a recipe for duxelles nor does he use this term).
